A poster is being designed with a height of (2x+6)cm and a width of (x+2)cm.
The printing cost is $0.75 per square centimetre.
a) Apply binomial expansion to find an expression for the printing cost of the poster.
(2x + 6)(x + 2)
0.75 (2x2 + 4x + 6x +12)
0.75 (2x2 + 10x +12)

A billboard has a length of (5x+2)m and a width of (x+1)m.
The rental cost is $10 per square metre.
a) Apply binomial expansion to find an expression for the rental cost of the billboard.
b) Calculate the rental cost when x=2.
10(5x2 + 5x + 2x + 2)
10(5x2 + 7x + 2)
= $36
